Most chemical compounds belong to either phenolics or flavonoids, known as potent antioxidants. This research explores the multifunctional potential as a bioactive cosmetic ingredient used in skin care for adding value to longan leaves. The dried powder of longan leaves was extracted with 50%(v/v) ethanol in de-ionized water, then quantified for total phenolic and flavonoid contents. The hydroethanolic extract was investigated for various antioxidant methods including DPPH, nitric oxide (NO) scavenging and lipid peroxidation inhibition assays. The anti-tyrosinase activity was also evaluated for skin-whitening properties. Furthermore, Anti-aging activity in term of antiglycation was also conducted. The high number of polyphenols within the extract possessed a high antioxidant potential with IC50 0.023 ± 0.002, 0.478 ± 0.033 and 1.495 ± 0.153 mg/ml for DPPH scavenging, NO scavenging and lipid peroxidation inhibition, respectively. The extract could inhibit the tyrosinase enzyme with IC50 4.90 ± 0.50 and 6.60 ± 0.18 mg/ml for L-tyrosine and L-DOPA as substrates. The extract also exhibited a potent antiglycation activity with IC50 0.023 ± 0.003 mg/ml. Moreover, it showed no irritation effect on the chorioallantoic membranes (CAMs) within 5 min using the Hen’s Egg Test-Chorioallantoic Membranes (HET-CAMs). In conclusion, the polyphenolic-rich longan leaf extract displayed a good antioxidant, anti-tyrosinase and excellent antiglycation potential with safety that could constitute a promising multifunctional bioactive ingredient for skin care cosmeceutical products.

Oral health related quality of life (OHRQoL) is defined as a multidimensional construct that reflects comfort of people when eating, sleeping and engaging in social interaction, self-esteem, and satisfaction with respect to their oral health. The aim of this study was to measure OHRQoL and its correlation with disease severity of patients with PV. In this cross-sectional study, OHRQoL was measured by chronic oral mucosal disease questionnaire (COMDQ) in 72 patients (45.91 ± 11.45 years old) with PV include 45 (62.5%) women and 27 (37.5%). Finally, the obtained data were analyzed by statistical software. The mean total score of COMDQ in patients with PV was 72.41 ± 9.23. Moreover, mean daily dose of prednisolone corticosteroid was 0.619±0.395 mg/kg. COMDQ score in women was significantly higher than men (P<0.001). COMDQ total scores significantly correlated with daily dose of corticosteroid (P<0.001). Our study suggested that OHRQoL in patients with PV was not acceptable, and it was worse in the female gender that have more severe disease. Therefore, medical management of the underlying disease, as well as social and emotional care facilities seem necessary to improve OHRQoL in PV patients.

Smith (Lepidoptera: Noctuidae) attack and to map patterns of single nucleotide polymorphism of the RGA genes. The study consisted of two activities, i.e., the field experiment to observe corn damage intensity and the laboratory observation to study the SNP pattern. Field experiment was conducted to compare eight corn varieties set in randomized block design with 3 replications. Damage intensity of the corn due to S. frugiperda attack was observed on the field and the corn samples were analyzed in the laboratory to examine the RGA (resistance gen analogue) which contained single nucleotide polymorphism (SNP). The results from the field and the laboratory analysis showed that the response of Bisi 321 variety to S. frugiperda attack was better than the other tested varieties. Based on the electrophoresis of the PCR results with the SNP2_MNBS_Alt primer, samples of corn varieties coded as V1 (Pertiwi 5), V3 (P-36), V6 (NK Super), V7 (Exotic), and V8 (Local) produced amplicons with the size of ±150 bp. The samples that did not have amplification were V2 (NK7328), V4 (Bisi 321), and V5 (Bisi 18). There is a possibility that the amplification results may indicate some degrees of tolerance clusters of corn varieties to S. frugiperda attack. Further validation is required to apply the SNP-based markers of corn to develop tolerant or resistant varieties.

PBSCs were separated and collected by leukapheresis before being cryopreserved and stored in liquid nitrogen. The number of CD34+/CD45dim cells was investigated and compared with the subpopulation of CD34+/CD38- cells using conventional trypan blue exclusion method and 7-AAD before and after cryopreservation.

The epiphytic bryophyte communities in FSM trial plots (13 and 21 years since tree planting), were compared with those of old-growth forest in the upper Mae Sa Valley, northern Thailand. Bryophytes were surveyed in June 2019, on the bark of 3 framework tree species: Archidendron clypearia, Erythrina subumbrans and Sarcosperma arboreum. Fifteen species were recorded, representing 14 genera and 12 families in 3 morphological groups: acrocarpous mosses 4 species (27%), pleurocarpous mosses 5 species (33%) and leafy liverworts 6 species (40%). Within 13 years after restoration initiation, bryophyte species richness had increased to the same level as that recorded in old-growth forest. Furthermore, the bryophyte community species composition of the older restoration forest was more similar to that of natural forest than was the bryophyte community species composition of younger forest. We conclude that the FSM effectively recovers bryophyte diversity and directs the successional trajectory of the bryophyte community towards that of old growth forest within an acceptable time span. The use of bryophytes as indicators of forest restoration progress is discussed.
